LIGHT-FOCUS SHADE OR DIMM'ER ZONE,

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed January a1, 1913. Serial a. 745,858.

To all whom it may concern:

Be it known that I, WILLIS J. PERKINS, a citizen of the United States, and a resident of the city of Grand Rapids, in the county of Kent and State of Michigan, have invented a certain new and Improved Light- Focus Shade or Dimmer Zone, of which the following, taken in connection with the accompanying drawings, which show a preferred form of my invention, is a speci cation.

This invention is a development of my invention disclosed in my former application, Serial Number 715,868, and the ob ect of this invention is to provide vehicles of transpor tation on land,"sea, or in the air, that have chauffeurs, pilots, guides or drivers, said persons being hereafter designated as rivers), to control their direction of' travel, speed or method of propulsion, or either, with a suitable device, which when placed before the-eyes of the driver through suitable manually operated means, provides said driver with a light intercepting shade or dimmer zone, through, over, under or around which observation may be made at the'optionofithe driver without his being blinded by natural or artificial lights, regardless of their brilliancy or focal intensity, in the act of meeting, passing or traveling toward said lights.

To th ese ends, I have made the invention consisting essentially of a means for dimming, screening or absorbing the focal rays of light in the visual range of the driver, such means being suitably attached to the vehicle of transportation or members thereof, and under control of the driver thereof to be adjusted by suitable manually operated means, and having construction such that when not in service it may be located entirely out of the way as in the daytime,

- thereinbeing shown some forms 0 or partially out of the way at night time and previous. to service adjustment, allowing freedom of visual outlook but subject to instant adjustment by the driver to place it in service protective or operative position, securing and providing'for the driver at all times, a clear visual outlook without the usual annoying and dangerous conditions produced by the focal glare of meeting or passing vehicles. f Various other objects and purposes will be apparent as the descriptions of the embodis ments shown in the drawings progresses,

practically applying my invention, although it is not attempted to show all of the many and various forms of applications that have occurred to me in reducing this invention to practical form.

In the drawings, Figure 1 is a side view of a portion of the fore part of an automobile with my invention applied thereto, the view being taken as from the left of Fig. 2. Fig. 2 is a view from the right of Fig. 1, showing the invention applied to an automobile having a right hand side drive and also provided with a wind shield. F 3 and 4 are views similar to Figs. 1 and 2 respectively, but illustrating my invention aoplied to an automobile having a left hand side drive. Fig. 5 is a view looking down on Fig. 4. Fig. 6 is a front elevation of the bracket and slide member by means of which my invention is attached to an automobile and is operated thereon. Fig. 7 is a sectional view taken on'the line a a, Fig. 6. Fig. 8 is a side elevation of a preferred form of column joint used in my device. Fig. 9 is a section on the line cc, Fig. 8. Fig. 10 is a section of the shade or dimmer zone proper, on the line ee, Fig. 2. Fig. 11 is a side elevation of the foot pedal by which the vertical adjustment of the zone is accomplished. ,Fig. 12 is a section thereof taken on the line 9-9, Fig. 11. Fig. 13 is a view similar to Fi 11 but from the opposite side of the pe al. Fig. 14 is a section as it appears taken on the line Fig. 13. Fig. 15 is a side elevation of the dimmer zone or intercepting shade and the supporting column therefor showing the column adjusted for the bowed-in type of wind shield. Fig. 16 is a side elevation of the zone or shade supported on a column having a different form of vertical adjustment from service to daylight or out-of-use position.

Similar reference numerals refer to similar parts throughout the several views of the drawings.

In the preferred form of my invention, I have shown its application to an automobile having a windshield. The device is wholly independent of the windshield, the same being merely illustrative, and the invention is applicable in suitable design for any vehicle of transportation, whether equipped with a windshield, or dash or not, and can be used whether or not the shield is in service position. In the preferred form shown, the automobile has the usual wind shield 1, of

any desired form or type secured in front of the post 2 and pilot wheel 3 in the usual manner. Back of the windshield I have positioned my dimmer zone or shade and it may be spaced any desired distance from the shield, said shield being foldable either to the front or rear as may be desired.

The zone is attached by means of a suitable bracket 4 to the vehicle, the faces 5 and 6 of the bracket being attached to the slide member 7 and to vehicle parts, respectively. Two different forms of brackets 4 are shown in Figs. 1 and 3, as suitable for application to diiferent portions of the vehicle, and in any event, the bracket 4 will be designed to fit the particular conditions of the vehicle so as to present a vertical face 5 against which the bracket and slide member 7 may engage. This member 7 is secured to the bracket 4 by means of bolts 8 Y which pass through slots 9 in the member 7 whereby said member 7 may have vertical adjustment with respect to the bracket 4 but be rigidly secured thereto in desired position.

The dimmer zone or shade proper is sup ported by a suitable vertical column 10 which in the forms shown in Figs. 1 and 4 is made up of a plurality of sections 11 hinged at 12 whereby the column may be folded into short compass when desired. The lower section is provided with slots 13, one in each edge thereof, in which engage the opposing slide members 14, which are attached to the member 7 as shown, the adjustment of the distance between the opposing slide members 14 being regulated by screws 15 hearing against and forcing one of the members 14 inward as shown in Fig. 7, a slot in said member allowing such adjustment.- This specific adjustment may be varied, it is evident, so long as the function of allowing the free sliding movement of the lower section 11 in a vertical direction is secured. At the lower end of the lower section, a link 16 is pivotally attached at one end while its other end is pivoted to the end of the arm 17, the other end of which is pinned to a short shaft 18 mounted in the casting 19, said casting being preferably secured to a fixed member of the vehicle, the floor being utilized in this instance as shown. The shaft 18 extends through the casting and has secured thereto on the opposite side of the casting. a pedal 20, the downward operation of which is designed to turn the shaft 18 on its axis to thereby lift the arm 17 and give vertical movement to the link 16 and the attached members against the weight thereof. The link 16 may be adjustable in length or of variable length so that the column may be supported above the floor the desired distance and the pedal and shaft support may rest on and be attached to the floor; and in difierent types of vehicles, the

link 16 may be of different lengths, this vari ation, however, being easily cared for.

The pedal 20 preferably carries on its side nearest the casting 19, an integrally formed dog 21 which is positioned to engage with ratchet teeth 22 located on the wing 23 of the casting, whereby when the pedal is depressed the dog engaging with the ratchet will serve to normally prevent the return of the dal to upper position, which under the in uence of the weight of the adjusted parts and of the torsional resistance of spring 24 surrounding shaft as shown in Fig. 12, it would tend to do. The construction by which the pedal is allowed to pass by the ratchet teeth and then engage therewith is illustrated in Figs. 13 and 14 and j shows the pedal pinned to the shaft 18 so as to have a limited lateral movement by turning about the pin, a spring 25 passing around the pin and having its ends engaging the shaft and the pedal serving to normally press the pedal against the wing 23, but yielding on the downward operation of the pedal to allow the dog to slip by the 1 teeth of the ratchet. If, however, it is desired to release from the ratchet for the return of the pedal, the operator may press laterally against the upstanding ledge or lip 26 cast integral with the pedal and operate the pedal to the side sufiiciently to separate the dog and ratchet thereby freeing the pedal to return to its initial or other desired position.

The intercepting shade or dimmer zone proper, denoted as a whole by reference numeral 26, is attached at the upper end of the upper section of the column. Various methods of attachment may be used, Figs. 1 and 2 showing the frame member 27 of the zone or shade secured in rigid relation to the upper section 11 by means of bolts, while in Figs. 3 and 4 the frame has pivotal attachment to the upper section at 28. Any suitable means of attachment as desired may be used. The zone illustrated in Figs. 1 and 2 is designed for use in machines having a right hand side drive, that is where the driver sits on the right of the car. In this country it is required that meeting vehicles shall turn to the right, and, accordingly, a driver of a machine must keep looking to the left in order to keep the vehicle he meets in view. It is evident therefore that he will seldom or never be troubled by lights on vehicles on his right to an extent preventing his protection by a slight shift of the head and eyes to the left and bringing the zone or shade in intercepting range with the focal rays the driver wishes to screen himself from. For the above reason, the zone need not extend to the right of a normally vertical line drawn midway between the drivers eyes, minimizing his shifting range for clearer vision ahead or vision through the dimer zone or intercepting shade. The right hand end of the zone may terminate substantially in the plane of the axis of the steering post, said axis being substantially a line rawn midway between the drivers eyes when in normal sitting posture at the steering wheel. Such plane or axis is indicated by broken line 00, in Figs. 1 and 2, and the supportin column may for convenience or artistic e ect be located some distance to the left of this plane. With the right hand drive the shade or zone proper consists of a frame member 27 which may for strength or otherwise be divided by a cross piece or tie 28' into two sections, in which is located a plate of suitable colored or tinted glass cel luloid, or other equivalent substance, or said trans-medium may be a continuous piece or multiple pieces. This medium when interposed in front of the eyw will intercept, absorb, screen or dim the light coming to the eyes, but will not cut out or eliminate all the rays of light or prevent a predetermined amount of observation through the same. The clearness of vision through the shade or zone is determined by the coloring or tint.

ing of the intercepting medium, according to the judgment and experience of the manufacturer or designer, and so proportioned as to prevent the driver from being blinded by exterior lights while reserving a sulficlentl clear vision to enable him to distinguish readily the passing vehicle and occupants therein. One method of attachment of the plates indicated at 29 to the frame 27 is shown in Fig. 10, there being a suitable recess formed in the frame around its edge in which the plate seats and a binding strip or member 30 placed thereover and secured to the frame by screws as shown. It of course is evident that many other methods of securing the plates in place will readily occur to those skilled in the art and I do not limit myself to this construction. The zone or shade extends to the left to the edge of the wind shield so that there is provided a lon dimming or shading portion to the left 0 the driver.

The hinging of the sections 11 of thesupporting column is accomplished by means of the hinge construction shown in 8 and 9, there being in effect a combined hinge and lock construction provided. The upper and lower sections'to eachside of the have each integral therewith cars 31 on t e upper section and '32'on the lower section which lie in different planes so as to pass by each other, and these ears areprovided with a'lining openings for the reception of the hinge pin or rod 33. A coiled spring of considerable strength is shown at '34 as lying between an ear 31' and an ear-32 and essing thereagainst and such sprmg'may inclosed in the sleeve-35 to add, a) the again in sition, the

appearance of the structure. A member 36 is attached by screw 37 to the upper section, and it has therein a plurality of recesses formed in its inner face and in which a pin 38 projecting from the lower section is adapted to seat. It is of course obvious that the position of the pin and member 36 on the sections of the column may be interchanged without difierence in functional operation. With this structure, and with the pin seated in one of the recesses of the member 36, there will be resistance made to the folding of the sections, as in order to accomplish the folding, it is necessary to compress spring 34 in moving the upper section and its attached member 36 sufiiciently to carry said member away from the pin and disengage the pin and recess. Then when the parts are turned to bring the pin in conjunction with another recess, the spring will act to frictionally and spring lock the parts lace. In this manner the sections of the co umn may be retained in a variety of ositions relative to each other, either wit all the sections in a line makin a vertical column, or with all of them fol ed into small compass, or with them as shown in Fig. 15, wlth the sections in different angular relations.

Without at present going any farther in the description of the structure, the operation of the device so far as set forth may now be described.

During the da ime, the dimmer zone or intercepting sha e will be of little or no use and at this time it is folded in compact form below the drivers normal visual range with the frame 27 taking the position shown in the lower dotted lines, Figs. 2 and 4. The hinges will retain the sections in folded position and the device as a whole will be out of the way, above any of the gages, speedometers, or other attachments usually found on such vehicle, yet low enough not to be objectionably noticeable. When the night time comes, the device is useful to its fullest extent, and at that time the column is unfolded, the operation thereof being shown in dotted outline in Fig. 3, and the zone takes the position shown in full lines, Figs. 1 and 2. This may be denoted as the preservice position of the zone, for in this posiglht is not obstructed in any manner by t e device, the plane of the drivers eyes being at.r-'r, Figs. 2 and 4. Snppom now, however, that the condition arises that the driver wants to screen his eyes from a brilliant exterior light. He immediately manually operates the means provided; and as. described heretofore, the

column'is given movement in a vertical direction, bringing the zone or shade to the upper dotted lmeposition shown which may be denoted .asthe protective service po- -sition,'in which position, the driver is protected from the focal glare of exterior lights. It will be noted that the driver has outlook around the end of the zone or shade due to the limiting of the length thereof to the right, but that by a very slight movementof the head, he may bring both eyes behind the zone at will, and that as the exterior li ht becomes nearer and passes to one side 0 the driver, he may follow it the length of the zone with his eyes and be protected from the focal blinding rays thereof until the lights have passed. It is to be understood in the use of the terms left and right that a construction is being described which will be used in those jurisdictions where meeting vehicles are obliged to turn out to the right, and that if, as in other countries, the rule was the other way. the zone would be correspondingly altered so that its major portion would extend to the right of the supporting column, the functions performed being the same. After the zone or shade is adjusted to focal protective service position, it may be left there as long as desired, the dog 21 in engagement with the ratchet teeth 22 holding it in upper position until by pressing the pedal laterally, it may be returned to pre-service position and left there until again needed.

In the operation of the column vertically in making the required adjustments, it is evident that there must be enough play to allow free movement of the sliding parts over each other without undue friction, and that any rattling will be objectionable. To provide for these conditions, I make the sliding parts wholly or partly of sound deadening or non-resonant material such that even though there is a little necessary contacting of parts, the effect thereof will not be noticeable. And with certain types of Windshields which do not occupy a vertical plane but are adjusted with sections thereof in different planes inclined to the vertical, the column is adjusted to correspond as shown in Fig. 15, the pivotal attachment of the zone to the upper section of the column allowing it to be positioned in a vertical plane irrespective of the inclination of its attached column section.

So far the description has had to do with the zone as constructed for a car having a right hand side drive. When it is apphed to a car having the left hand side drive, modifications of the zone are desirable owing to the different conditions encountered. The driver sits on the left and nearer the vehicles that he meets, and the protective zone or shade must be extended to the left for his protection beyond the edges of the windshield or the vehicle side, and it is preferable that this portion beyond the shield or side shall be capable of retraction within the side limits of the vehicle so that it can be put out of the way when not in use. To serve these ends, I have modified the construction of the protective zone proper as shown in Figs. 3. l and 5, the frame being divided near the side edge of the windshield and the left hand portion 39 thereof pivoted to the relatively stationary section -10. so that it may fold thereon and occupy about half the normal unfolded space. In the daylight folded adjustment of the device, the zone proper occupies a position as shown in the lower dotted lines in Fig. 4. or the position may be varied as desired by changing the lengths of the sections 11 of the supporting column. When in position for use. the hinged section 39 is turned to its open position. and is held there by use of the same or an equivalent structure that is used in holding the sections of the column in proper positions. said open position of the zone 'not being with the sections thereof in a straight line but with the hinged section 39 lying forward at an angle to the relatively fixed section 40, whereby the hinged section need not be as long for the protection of the driver as would be the case if the sections were in the same plane. The hinge is positioned so as to lie practically in front of the frame of the windshield when the driver looks at an an le which includes the windshield frame in liis vision. to thereby have as little obstruction to the vision as ossible. Spring 41 performs the same unction relative to the hinging and locking of sections 40 and 39 as does spring 3t with reference to column sections 11.

It is not necessary that the column shall be folded in order to carry the zone to daylight retracted position but the same result may be secured by making the column sections telescopic as shown in Fig. 16 wherein is shown the sections 42 mounted to be extended to full length position when in use. but adapted to be telescoped to occupy little vertical space and with the zone carried therebv in daylight in operative position.

Various other suitable modifications will occur to those skilled in the art.

The operation of the self-protective zone with the left hand drive. excepting for the folding and unfolding of the hinged section. is identical with that previously described relative to the right hand drive. In both instances. it is clear that the zone has three adjustments. namely. the daylight out-ofservice adjustment. the operative pre-service adjustment. and the operative focal protective adjustment. the first being that used when the zone is not in operation at all. nor needed: the second being that used when driving with a clear field ahead and no exterior lights in view: and the third used when an exterior light is met. to thereby shield the eyes of the driver and allow him unimpaired vision at all times. And the operation from pre-service to service adjustment is always under the control of the driver as well as the return from the service to pre-service adjustment. The folding of the column or the unfolding thereof is accomplished manually, and there may be provided a handle for ready engagement, on the frame of the zone or shade, indicated at 43, whereby the folding and unfolding may be rendered easier.

I have fully disclosed my invention and indicated some operaitve constructions by which it may be embodied. Such constructions are not the 0111 ones that may be utilized to reduce my invention to ractical form, however, and I consider myse f as entitled to all variations in structure and substitutions of equivalent parts which fall within the scope of the appended claims and do not depart from the spirit of the invention.
